A
Dial connected to the tank measuring the amount of oxygen in the tank.
What is pressure gauge?
Measures the liters of oxygen per minute that is delivered to the patient
What is the flow meter?
A button or lever that when used delivers pure oxygen to the patient fills and empty reservoir bag but will dilute the concentration of inhalant in the circuit.
What is the oxygen flush valve?
Holds liquid anesthetic and delivers the evaporated gas at a precise amount in %.
What is a vaporizer
The exit point where fresh gases (O2 and anesthetic) leave the precision vaporizer and connect to the fresh gas inlet
What is the common gas outlet
A system which includes a fan or vacuum unit to draw gas outside.
What is an active scavenging system?
System that relies on the positive pressure within the anesthetic machine to push WAGs outside or through a charcoal canister
What is a passive scavenger system
Overfilling the reservoir bag and damaging the patients lungs will result in.
What is barotrauma?
Point at which gas enters the breathing system
What is the fresh gas outlet?
removes the exhaled CO2 from the breathing circuit
What is a CO2 absorbent can?
Measures the pressure within the breathing system (including the patients lungs.) Used to monitor pressure during anesthesia and when administering IPPV
What is the manometer?
Allows gases to travel in only one direction through the circle preventing rebreathing of unfiltered gases.
What are the inhalation and exhalation valves (uni-directional)?
Commonly referred to as a “circle” system as gas travels in a virtual circle to and from the patient
What is a rebreathing system/circuit?
Patient breathes in only fresh gases (oxygen and anesthetic), and all exhaled gases leave the system via the exit port to a scavenger.
What is a non-breathing system/circuit?
Used to vent excess gases and pressure from the circle/circuit to the scavenger. Should be fully open during most anesthetic procedures.
What is a pop-off valve?
An orthopedic instrument, used to scrape hard tissue, bone or cartilage. "ice cream scoop"
What is a bone curet?
Scissors used to cut through delicate tissue (fat, thin muscle), straight or curved, rounded points, never used for cutting suture.
What are metzenbaum scissors?
Instrument with intermeshing teeth with a broad tip for good tissue and suture needle handling.
What are Brown-Adson forceps?
Forceps which has transverse grooves extending the entire length of the jaws.
What are Crile hemostatic forceps?
Instrument used to clamping across tissue that contain vessels (crush), have longitudinal grooves and a cross-groove at the tip for greater traction.
What is Rochester-Carmalt?
Each individual suture is placed separately with its own knot so failure of one suture does not result in failure of the entire line
What is simple interrupted?
pattern starts by creating a simple interrupted pattern but instead of tying the suture, the needle is inserted 6-8 mm laterally on the same side as the needle exited, it crosses to the other side of the incision to exit. The suture ends (which should both be on the same side of the incision) are then knotted.
What is horizontal mattress?
pattern is similar to the simple interrupted pattern after tying the first knot, the suture is not cut and the bites are continued on each side of the incision until the end of the incision line.
What is simple continuous?
Technique is used at the end of a hollow organ stump or around a tube being placed in a hollow organ or a cavity. may be used to close visceral stumps and to secure percutaneous tubes into a viscus such as may be seen in gastrostomy and cystostomy procedures
What is a purse string?
Created by passing a length of suture material around a clamped pedicle twice to create two loops, with the second loop overlapping the first. (OHE)
What is a millers knot?
